STEEL CONTAINER;

'A application :um March 24,1922. serirNp. 546,234.

To all whom it may con cem p n Be it known that I, SHERMAN G: LONG,

a citizen vof the United States, a resident of Peoria,in the county of Peoria and State of Illinois, have invented new and useful Improvements in Steel Containers, of which the following is ay specification. y

This mv'ent1on hasy reference to 'improvelments in steel Acontainers of `various types,

The invention has fora further object to vflange the opening.' in the containerl preferably' by stamping or punching and to'provide an internally threaded drop-for ed, vcast or punched ring, preferably welded to the flange ofthe container'for permanently securing the samev thereto; such ring being provided with radially arranged depressions' or corrugations for, purposes of draining. A screw plug .being provided which is adapted to engage the threads vof the ring to closethe opening.

That the invention may be more fully understoodreference is had to the accompanying drawings forming a part vof the present description, illustrating a preferred embodiment of. theinvention', in Which'z- Figure 1 is a longitudinal sectional view on a somewhat reduced Ascale showing nmy improved opening in' the wall of a metal container and the 'screw closingplugthereof, the View also illustrating ythat when used on ribbed or corrugated containersl the plug does not interfere with therolling of the container; i

Figure 2 isa' plan view, approximately full size, showing the face of the'ring secured to the container andl provided with or corrugations; f Figure 3 is a cross-section -as the same would appear if taken on the line 3 3 Figure 2, the ring and flange of the container being preferablywelded together;

Figure 4 is a view similar to Figure 3 except that the vring vand flange have not been welded;

Figure 5 is a plan view of the screw plug adapted to have a threaded connection with the ring, and provided with a perforated ear or lip for the attachment of a` shipping-tag thereto, and v y y Figure is a cross-section on the line 6,-6

Figure 5. f fr Like characters'fof'reference denote corresponding parts throughout the figures.

The invention is most useful in connection withfmetal barrels,although adapted to metalor steel containers, tanks,etc., and I therefore, Wish it understood that although described in connection-with metal barrels there is no intention' to so limit the use of the invention.V j

y In Figure l the wallof a metal barrel is designated 1 and is shown provided with an annular corr-ligation or depression 2 providing a strengthening rib for suchy barrel. In practice there are two or'more such ribs provided Ain the'--b`arre,l. AAt any suitable point, the barrel is-provided withv a flanged opening 3 punched lor stamped therein, with the flange projecting 'outwardly andv prefer'- ably at approximately lright angles to the body of the barreland acts as a reinforcement thereto.` I have shown the flanged Opening, referably in the sidewall ofthe barrel mi Way itse'nds, but it is to be understood such' flanged opening may be in either end of the'barrel, yorfat or near the ends in the side wall, or one or more such openings provided, if desired. f

4 designates an internall threaded ring, which `may be a drop forgmg, casting or a machine punched ring and said lring is formed with an annular depression 5 on one face producing the marginal flange 6, which,

when the ring-fis inserted into `the flanged opening in the Wall of the container lwill lie in juxtaposition tothe flange 3, as shown in Figure 4, and to be welded-thereto, as at 7 and as shown inFigure 3, by an acetylene torch'or in 'any other suitable manner.' The opposite face of.' the ring, preferably ythat.

flange 3, by vtilting the container,"as will be understood. l

Having a screw connection with the in'- ternallyarranged threads'in the ring 4 is a plug 9 for closing the opening in the container. Such plug has a polygonal shaped flangesl() to be gripped by a suitable tool and also a rectangular socket 11 for the insertion of a suitable tool, whereby the plug may be screwed into and unscrewed froml the ring 4.-. Also, said flange 10 has a perforated ear 12 to provide for the attachment or connection of a shipping tag, as will be understood. A gasket l3'being interposed between the flange of the plug and the ring to provide a leakage proof closure.

By reference to Figure l, it will be observed that my inventio when applied to a metal barrel will in no-wise interfere with therolling of the barrel, as the construction of the flange 3, ring 4? and plug 9 1s of such a character that they project from the barrel well within the depth or thickness of the ribs 2.

Furthermore, while I have described a ring formed or provided with depressions, grooves or corrugations such as 8, welded to the flange 3, it is to be understood that the flange 6 of the ring 4 and the flange 3 of the barrel could be lock seamed or otherwise suitably connected.

What I claim is:

l. In a metal barrel provided with annular corrugations and an annular flanged openingA in its corrugated wall pro]ecting outwardly less than the depth of such corrugations, of an internally threaded ring adapted to fit within said flanged opening and provided with an encircling ange of less depth than the width of its threaded portion and of approximately the thickness of the wall of said flanged opening and secured thereto, and the inner face of said ring provided with a plurality of radial draining depressions the base 'walls of which normally lie a proximately in the plane of the outer sur ace of the barrel to insure thorough draining of material contained therein.

2. In a metal barrel provided with annular corrugations and an annular flanged opening in its corrugated wall projecting outwardly less than the depth of such corrugations, of an internally threaded ring adapted to fit within said flanged opening and provided with .an encircling flange of less depth than the width of its threaded portion and of a proximately the thickness of the wall of said flanged opening and secured thereto, and the inner face of said ring provided with a lurality of radial. draining depressions t e base walls of which ,normally lie approximately in the lane of the outer surface of the barrel t0 insure thorough draining of material contained therein, a threaded plug arranged to have connection with the threads in said ring and provided with a tool engaging portion, and a gasket to lie between the tool engaging portion of said plug and the main body portion of said ring to seal the connec tion. i

3. In a metal barrel provided with annular corrugated strengthening ribs, a flanged opening in the corrugated wall the flange of which is of less depth than said corruga tions, an internally threaded ring arranged to fit within said flanged opening, its main body thickness being of greater depth than the flange of said opening and encircled by a flange partially spaced from the body of the ring and of approximately the thickness of the flange ofsaid opening and secured thereto, the formation of the flange of said opening and said ring at the base ofthe flange leaving a space therebetween, and the inner face of `said ring provided with a plurality of radially arranged draining depressions the base walls of which lie approximately in the plane of the outer surface of the barrel to insure thorough draining of material contained therein and settling in the space between the flange of the opening and said ring.

4;. In a metal barrel provided with annular corrugated strengthening ribs, a flanged opening in the corrugated wall the flange o which is of less depth than said corrugations, an internally threaded ring arranged to fit within said flanged opening, its main body thickness being of greater depth than the'flange of said opening and encircled by a 'ange partially spaced from the body of the ring and of approximately the thickness of the flange of lsaid opening and secured thereto, the formationvof the flange of said opening and said ring at the base of the flange leaving a space therebetween, and the inner face of said ring provided with a plurality of radially arranged draining depressions the base walls of which lie approximately in the plane of the outer sur- .face of the barrel to insure thorough drain- 111g of material contained therein and settling. in the space between the flange of the opening and said ring, a threaded plug arranged to have connection with the threads 1n said ring and provided with a tool engaging portion, and a gasket to lie between the tool engaging portion .of said plug and the main body portion of said ring to seal the connection.

In witness whereof, I have hereunto afby hand this 22nd day of March,

SHERMAN G. LONG.
